I'm not very good with mutations but I just wanted to say that both these budgies are absolutely gorgeous! I especially love the green colouring on the second one. Hopefully one of our genetic pros can help you. In the mean time, have a look through the Budgie Mutation and Colour Guide and you should be able to figure out their specific mutations. Also the blue budgie looks older than 3 months, he looks more like he's at least 4 months, just by looking at how much the barring on his head has receded.
